Women, many of them mothers and daughters, participate in the 10th annual Mother's Day Fancy Dress Swim, which raises funds for the Against Malaria Foundation, at the Oceanside Pier on Saturday, May 12, 2018. One hundred percent of the funds raised from the event will go to long lasting insecticide treated bed netting. According to the Against Malaria Foundation's website, malaria is the number one killer of pregnant women in areas of the world affected by the mosquito-borne disease.
